Fixed to each of the channels 1 and 2 1s 'a cross channel 3. Located above the channels 1, 2 and 3 are parallel angle irons 4 which are supported upon the body frame of the motor vehicle (1n a way not shown) and upon said, angle none 4 is supported the floor 5. Also supported upon the angle irons 4: is a base plate 6. Upon this base plate 6 is secured an uprlght frame or standard 7. Extending vertically in the standard 7 is a shaft 8which is surrounded bythree concentric hollow shafts or pipes 9, 10 and 11. The shaft 8 fits change speed and reversing gearing of the I closely in the smallest pipe 9, but loosely, so

The lower section 12 of said casing coniprises a disk 13 which has an integral flange 14 extending upwardlyaround the edge of 1 said disk.- The largest pipe 11 extends through a flanged opening in the disk 13 a for a short distance above said disk 13, and

to said projectin end portion of the largest pipe 11 is fixe a rectangular block '15. Straddling the block 15 at each end is the bifurcated end of a hand lever 16. For convenience in description the hand levers 16 will be hereinafter termed reversing flevers. Each branch 17 of the bifurcated ends of each reversing lever 16 is pivoted to the block 15 by a bolt 18which extends transversely of said block 15 near one end. Each branch 17 of each reversing lever 16 has a'number of gear teeth thereon, and the gear teeth of the corresponding branches 17 mesh. Disposed above the bolts 18 and near each longitudinal edge of the block 15 is a compression coiled spring 20, the ends v of which engage the reversing levers 16 and tend to move the handles of said reversing levers downwardly. In the upper edge of the flange 14 of the lower section 12 are two notches 21 located diametrically opposite to each .other. The notches 21 are about as wide as the reversing levers 16 so that said reversing levers may drop into said notches. Located on each side of each notch 21 is a shoulder 22 in the flange 14 of the lower section 12.

Above the lower section 12 of the casing 7 lower intermediate section 23 which comprises a disk 24 having along its edge an upwardly pro ecting flange 25 and a downwardly projecting flange 26. In the downwardly projecting flange 26 of said disk 24 are long notches 27 which are located diametrically opposite to each other. Each of said long notches 27 is located above one of. the notches 21 in the lower section 12 and extends beyond each shoulder 22 of the lower section 12 for a distance about equal to the width of the'reversing levers 16. The portions of the downwardly projecting flange 26 of the lower intermediate section 23 between the'long notches 27 rest upon the portions .of the flange 14 of the lower section 12 between the shoulders 22.

The pipe or hollow shaft 10 extends througha flanged opening in the disk 24 of the lower intermediate section 23 for a short'distance above said disk 24, and fixed to the projecting end portion of said pipe 10 is a rectangular block 28. Straddling the block 28 at each .end is the bifurcated end of a pivoted member or dog 29. The bifurcated ends of the dogs 29 are pivoted to the block 28 by bolts 30 extendingtransversly of said block near each end thereof. In the upper face of the outer end portion of 66 each dog 29 is a longitudinal groove 31.

secured to the top of the standard 7 is a' Disposed below. the bolts 30 and near' eachlongitudinal edge of the block 28 is a compression coiled spring 32, the ends of which engage the dogs,29 and tend to move the outer end portions of said dogs upwardly.

Each branch 33 of the bifurcated ends of the dogs 29 has a number of gear teeth levers. Each branch 37 of the bifurcated end of each speed changing lever 35 is pivoted to the block 34 by a bolt' 36 passing transveresly of said block 34 near one end thereof. Each branch 37 of the bifurcated ends of the speed changing levers 35 has a number of gear teeth thereon, and the gear teeth on the ends of the corresponding branches mesh.

The intermediate section of the casing secured to the top of the standard 7 comprises v two curved members 38, approximately semicircular. One of said curved members 38 is 95 located upon each side of the block 34 and the speed changing levers 35; and between the corresponding ends of said curved members 38 is a space equal to the width of the speed changing levers 35. Near each .end of each curved member 38 on both the upper and 'lower edges thereof is a shoulder 39. The corresponding shoulders 39 are spaced apart equal to the width of the outer ends of the dogs 29. On each side of each end 05 of each curved member 38 in both the upper and lower faces thereof is a notch 40 having a width" equal to the width of the outer ends of the dogs 29.

' Fixed upon the upper end portion of the smallest pipe 9 above theblo'ck 34, to which tions of the dogs 43 downwardly. In the under or lower face of the outer end portion of each dog 43 is a groove 44*.

The upper section of the casing secured to the top of the standard 7'romprises a plate 46 which hasa downwardly extending flange 47 along its edge. Through the plate 46 passes the shaft 8' which extends some wheel 48.

distance above said plate 46' and which has fixed to its upper end portion a steering Surrounding the shaft 8 and located above the plate 46 is a loose'sleeve 49. Secured to the Sleeve 49 near its upper end are two,

armsor handles 50 which extend in opposite directions from said sleeve 49. Surrounding the sleeve 49 .and fitting loosely thereon is a second sleeve 51 which is shorter than the sleeve 49. 'Secured to the second sleeve 51 near the upper end thereof are two arms or handles 52 which also extend in'opposite directions from said second sleeve 51. Secured to the sleeve 49 near its lower end is a gear 53, and secured to the second sleeve 51 near its lower end is a gear 54. Projecting upwardly from the plate 46'is a rectangular casing 55 which incloses the gears 53 and 54. Secured to the casing:55 are two springpressed pins 56, the ends of which are conical and engage between the teeth of the respective gears 53 and 54. Fixed to a shaft 57, which is journaled near its upper end in the plate 46, is a sector-gear 58 whlch meshes with the gear 54 fixed to the second sleeve 51. Fixed to a shaft 59, which is journaled near its upper end in the plate 46, is a sector-gear 60 which meshes with the gear 53 secured to the sleeve 49. The shafts 57 and 59 extend vertically and downwardly within projecting'pipes 61 through the base plate 6 and terminate a short distance below said base plate. To the lower end portion of each shaft 57 and 59 is fixed an arm 62. To the arms 62 are connected rods (not shown) which lead respectively to the throttlefor the carbureter of the motor which drives the vehicle and to the spark control of said motor.

' The lower section 12, the lower intermediof two opposite sides, in each of which bosses is a circular hole. The circular holes in the corresponding bosses 63 aline, and through'them pass lon' screws 64 which serve to secure the di erent sections to gether. The lower section 12 is fastened to the standard 7. Upon the rectangular casing 55 of the upper section is secured a cover plate 65.

In the base plate 6 which su ports the standard 7, is a circular opening li upwardly extending annular flange surrounding it, and mounted to turn in said opening is a hollow shaft 66. The largest pipe 11, together with'the pipes 10 and 9 and the shaft 8 mounted therein, passes through the bore of the hollow shaft 66. Below the base plate 6 is acastin 67 which is cured thereto. The casting-67 and the base aving an plate 6 are fastened together by long screws 68 which pass through the downwardly projecting bosses 69 integral with the base plate 6. In the casting 67 are ,two vertically spaced bearings 70 through which the shaft 8 passes.

Integral with the hollow shaft 66 near its upper end and above the base plate 6 is a bevel-gear 71. On each side of the hollow shaft 66 and the bevel-gear 71 are two spaced bearings 72. In each pair of said bearings 72 is journaled a rock-shaft 73. Each rock shaft 73 has an enlargement-74 between its ends which has an opening therein through which one of the pipes 61 passes. The rock shafts 73 can rock through a small angle relative to the pipes 61. To each "rock shaft 73 at one end is fixed a sector-bevel-gear 75,

and these sector-bevel-gears mesh with the bevel-gear 71 on opposite sides thereof. To each rock shaft 73. near the end opposite the end to which said sector-bevel-gear 75 is fastened, are fastened two pedals 76 which extend from said rock shaft 73 in opposite directions. The pedals 76 extend from the rock shafts 73 at different angles. Consequently, when one pedal 76, secured to one of the rock shafts 73 and extendin to one side of said rock shaft 73, is up; t epedal 7 6-secured to the other rock shaft 7 3 and extendingto the same side of the rock shaft 73, isdown, and vice versa.

To the hollow shaft 66 near the lower end thereof is fixed a crank-arm 77. A lever 78 is pivoted near one end thereof upon a'screw 79 fastened to the base plate 6 and the casting 67. To the other end of the lever 78 is pivoted one end of a link 80, which is pivotally connected at its other end to the crank arm 77. is pivotally connected one end of an adjustable link 81',' and-the other end of said ad- 3' ustabile link is pivotally connected to a crankarm 82 fixed to a rock-shaft 83 which is mounted in bearings 84 secured to the channels 1 and 2. The rock-shaft 84 is suitably connected to the clutch (not shown) which,

as in the usual construction of motor vehollow shaft 66 for a short distance below the arm 77, and to this projecting portion of the largest'pipe 11 is fixed a member comprising a sector-bevelgear 8 5 and a sector 86 having three notches 87 therein. The sector-bevel-gear 'and the notched sector 86 extend in opposite directions from the largest pipe 11. The pipe 10 extends for a short distance below the end of the largest pipe 11 and has fixed thereto a member comprising a sector-bevel-gear 88 and a sector 89 having three notches 90 therein, said' sector-'bevel-gear 88 and said notched sector distance below the en .coil spring 112- surrounding 89 extending in opposite directions from said. pipe 10. The smallest ipe 9 .extends a short d of the pipe 10 and has fixed thereto a member comprising a sector-bevel-gear 91 and a sector 92 having three notches 93 therein; said sector-bevelgear 91 and said notched sector 92 extending in opposite directions from the smallest pipe 9. The sector-bevel-gears 85, 88 and 91 are successively smaller in diameter so that their teeth lie in the surface of a cone. The lower member fixed to the smallest pipe 9 rests upon the upper bearing in the casting 67. The notched sectors 86, 89 and 92 which are secured to the three pipes 11, 10 and 9 respectively, have their outer edges in a vertical plane. The threenotches 87, 90 and 93 in the sectors 86, 89 and 92 respectively are spaced the same distance apart in each of said sectors, and in the different operative positions of said sectors said notches aline vertically. Upon the lever 78 is a locking tongue 94 which is adapted to move in and out of the alined notches in the sectors 86, 89. and 92.

Meshing with the sector-bevel-gear 85 .is a sector-bevel-gear 95 which is fixed to a hollow shaft 96 near one end thereof. Meshing with the sector-bevel-gear 88 is a sectorbevel-gear 97 fixed to a hollow shaft 98 near one end thereof. Meshing with the sectorbevel-gear 91 is a sector-bevel-gear 99 which is fixed to a shaft100 near one end thereof. The shafts 96, 98 and 100 are concentric. The shaft 100 is journaled at one end in the bearing 101, preferably formed integral with thecasting 67, and at its other end in a bearin 102 fixed to the cross channel 3. To each 0 the shafts 96, 98 and 100 is fixed an arm 103. The arms 103 are each pivotally connected to a sleeve 106. Extending through each sleeve 106 is a rod 107. The operative connection between the sleeves 106 and their respective rods 107 is the same; and the description of one will suflice for all. About each of the rods 107 are collars 108, through each of which passes a pin 109. Each pin 109 passes through a slot 110 in the rod 107. The collars 108, when the pins 109 therein are in contact with the adjacent ends of the slots 110, are in contact with the ends of the sleeve 106. Spaced from each collar 108 is a second collar 111 which is pinned to the rod 107. Between .each collar 108 and the corresponding collar 111 is a compression the rod 107. The rods 107 are connected in any suitable way to a reversing gearing and change speed gearing, which usuall constitutes part of the transmission mec anism between the clutch and the wheels of a motor vehicle. This reversing gearing and change speed gearing forms no part of the present invention and is not shown. The control for Inotor vehicles which is shown has been despeed gearing of the clutch type in which there are four speeds forward and four speeds backward. V

To the shaft 8, near its lower end, is fixed a bevel-gear 113. Below the bevel-gear 113 is a horizontal shaft 114 upon which are loosely mounted two bevel-gears 115 which mesh with the bevel-gear 113 on opposite sides thereof. Upon the inner face of each bevel-gear 115 are clutch teeth 116. Located between the bevel-gears 115 is a clutch collar 117 which is splined upon the shaft 114 so that it can slide thereon but must turn therewith. The clutch collar 117 is adapted to engage the clutch teeth 116 on either of the bevel-gears 115. Connected to the clutch collar 117 is an arm 118. The arm 118 is fastened to a horizontal shaft 119 near one end thereof, said shaft 119 being located below the shaft 114. Fastened to the horizontal shaft 119 near the other end thereof is an upwardly extending operating arm 120, which passes through a slot 121 in the base plate 6. Near each end of the slot 121 a spring-pressed pin 122 is secured to the base plate 6. The spring-pressed pins 122 have pointed ends which are adapted to engage a recess in the outer face of the operat ing arm 120, when said arm is at either end of the slot 121. 'To the horizontal shaft 114 is fixed a gear 123 which meshes with a larger gear, 124. The larger gear 124 is fastened to a shaft 125 near one end thereof, said shaft 125 extending parallel to the shaft 114. Near the other endof the shaft 125 is fixed a worm 126. Located above the shaft 125 and extending at right angles thereto is a horizontal shaft 127 to which is fastened a worm-sector 128, meshing with the worm 126. To the horizontal shaft 127 is fixed a downwardly extending arm 129 to which is connected in the usual way a link (not shown) which is connected to the steering wheels of the motor vehicle. The bevelgears 113 and 115 'areinclosed in a casing 130 which is adapted to contain a lubricant. The gears 123 and 124 are also inclosed in a casing 131 for containing a lubricant, which is connected to the channels 1 and 2 by the integral bracket members 132. The worm 126 and the worm-sector, 128 are also inclosed in a casing 133 for containing a lubricant, which is supported by the channels 1 and 2. I

The control'shown and described is designed for use in connection with a motor vehicle driven by a gasolene motor in the usual way. The levers 50, which are integral with the sleeve 49, control the throttle of the c'arbureter. of the motor. These levers 50 project in opposite directions from the sleeve 49 and consequently the operator moves each lever 50 in the same direction whether he is seated in front or in back of the standard 7. The throttle is connected as is apparent. The levers 52 which are into the arm 62 secured to the lower end portion of the shaft 59, and the shaft 59 is turned when the levers 50 are moved by means of the gear 53 andthe sector-gear 60,

tegral with the sleeve 51 control the ignition of the motor. The ignition controlling device is connected to the arm 62 fixed to the lower end portion of the shaft 57, and the shaft 57 is turned when the levers 52 are moved by means of the gear 54 and the secthe gears 53 and 54 and serve to retain the throttle lever 50 and the spark lever 52 respectively in the different positions in which they are placed by the operator.

In order to make the operation of the control clear, the manipulations necessary to start the motor vehicle will be described. The reversing lever 16 and the speed changing levers 35 are assumed to be in their neutral positions, that is, the reversing levers 1.6 are in. the notches 21 and the speed changing levers 23 are in the spaces between the ends of the curved members 38. The gasolene motor is started, and the clutch is thrown out of its operative position by depressing the right-hand pedal 76. When the right-hand pedal 76 is depressed, the

hollow shaft 66 is partially rotated by the sector-bevel-gear' and the bevel-gear 71, and the crank-arm 77 is swung through a small angle. .The lever 78, being connected to the crank-arm 77 by the link 80, is also swung, and the rock-shaft 83 is operated by means of the link 81=and the crank-arm 82. Referring to Fig. 13, the crank-arm 77 is in the position in which the clutch is in its operative position, and said crank arm is swung in a counter-clockwise direction to throw the clutch out of its operative position; When. the right-hand pedal 76 is depressed; the crank-arm 77-is swun to the opposite side of the straight line between the axis of said crank-arm and the center of the pivot which connects the link 80 to the lever 78. The spring upon the clutch, which tends to return the clutch to its operative position, will then tend to swing the crank arm 77 farther in a counter-clockwise direction; but since the crank-arm 77 strikes the lever 78, said spring cannot move the crank-arm 77, and the clutch is retained out of its operative position.

When the lever 78 is swung to throw the clutch out of its operative position, the locking tongue 94, integral with said lever, is withdrawn from the notches 87-, 90 and 93, in the sectors 86, 89 and 92, which are fastened to the pipes 11, 10 and .9 respectively, and the pipes 11, 10 and 9 are free to move.

Assuming that the operator is facing forward, he unlocks the reversing lever 16 projecting rearwardly from the standard 7 by lifting said, reversing lever from the notch levers 16 are connected by the gear teeth, when one of said reversing'levers 16 is lifted from its notch 21, the other reversing lever is also lifted from its notch 21. After the reversing lever 16 has been unlocked the operator swmgs it to the right or left, depending on the direction he wishes to drive the motor vehicle. The reversing levers 16 swing simultaneously and turn the block 15, which turns the. largest pipe 11. The largest pipe 11 rocks the hollow shaft 96 by means of the sector-bevel-gears and 95. When the hollow shaft 96 is turned, the arm 103 connected thereto moves the sleeve 106 along the rod 107 in the direction depending upon the direction in which the hollow shaft 96 turns. The sleeve 106 is moved a distance about equal to the. length of the slots 110 in the rod 107, and the spring 112 is compressed. If the. arts of the reversing gearmg, such as t e sliding gears, sliding.

clutches or the like which, engage each other, are in the proper position .to engage with each other, the rod 107 is immediately moved by the spring 112 to engage said parts with each other. However, if said parts of the reversing gearing are not in the proper position to engage with each other,-

the spring 112 is compressed; and when the clutch is thrown into its operative position, and the parts of the reversing gearing moved, the spring 112 will snap said parts into engagement with each other when said parts have been moved to the position where they can engage. After the operator has moved the reversing lever 16, he releases it,

and the springs 20 press said reversing levers downwardly between one of the shoulders 22 and the corresponding end of the 7 long notch 27, thus locking them.

The manipulations so far described place the reversing gearing in the osition to move the motor vehicle either orwardor backward. The next manipulations are those which operate the change speed gearing to secure the desired ratio of speed between the motor shaft and the wheels of themotor vehicle. The control shown and described is designed for controlling four speeds, that is, four different ratios between the motor shaft and the wheels of the motor vehicle. All of the four speeds are con-' trolled by the speed changing levers 35. The neutral positions of the speed changing levers 35 is shown in Fig. 2, in which said speed changing levers are in the spaces be tween the ends of the curved members 38, and the dogs 29 and 43 are engaged with the shoulders 39. Two of the four speeds are controlled by the smallest pipe 9, and the other two speeds are controlled by the pipe 10.

To obtain the first or lowest spd, the

operator lifts the speed changing lever 35 nearest to him from the space between the ends of the curved members 38 into the notch 44 in the under face of the outer end portion of the corresponding dog 43. The continued upward movement of the speed changing lever 35 rocks this dog 43 until it clears the shoulders 39. Since the dogs 43 are connected by the gear teeth, when the outer end portion of one dog 43 is raised, the outer end portion of the other dog is also raised. Both speed changing levers 35 being thus unlocked, the nearest one is then swung sidewise in the direction desired, which in the present construction for the first speed, is to the left. The dogs 43, the block 41, and the smallest pipe 9 are moved when the speed changing levers 35 are moved. The turning of the smallest pipe 9 turns the hollow shaft 100 by means of the sectorbevel-gears 91 and 99.

gearing of the transmission mechanism is set so that the motor vehicle will move forward at the first or lowest speed. The left-hand pedal 7 6 is then depressed, and this releases the locking action between the crank arm 77 and the lever 78. The spring upon the clutch, aided by'the pressure upon the lefthand pedal 76, throws the clutch into its operative position and connects the wheels of the motor vehicle to the motor. When the left-hand pedal 76 is depressed, the

locking tongue 94 of the lever 78 moves in the notches 87, 90 and 93 in the sectors 86, 89 and 92, and holds the shafts 11, 10 and 9 respectively against turning.

It is desirable that the operator who is facing in the direction in which the motor vehicle is traveling should turn the steering wheel 48 in the same direction whether said motor vehicle is traveling forward or back bevel-gear 115. When the clutch collar 117 a The shaft 100 is operatively connected to one of the rods 107,

is in engagement with one of the bevel-gears 115, the shaft 114 turns in one direction relative to the steering wheel 48, and when the clutch collar 117 is in engagement with the other bevel-gear 115, the shaft 114 turns in the opposite direction relative to said steering wheel. The shaft 114 drives the shaft 125 by means of the gears 123 and 124 and the shaft 125 drives the shaft 127 by means of the worm 126 and the worm-sector 128;

Thus, the arm 129 is moved when the shaft 127 is turned and operates the steering devices of the motor vehicle. The springpressed pins 122 retain the arm 120 at either end of the slot 121 by engaging in the recess in said arm.

Some motor vehicles, such as tractors used for farming purposes and the like, are driven backward-in use as well as forward; and where such a motor Vehicle is driven backward for a considerable time, it is difficult for the operator to face forward and control the motor vehicle while it is traveling backward. The control shown and described obviates this objection and permits the operator to face in the direction in which the motor vehicle is traveling, and to operate all of the usual controlling devices, irrespective of whether a motor vehicle is traveling forward or backward. This is made possible in the control shown and described because the controlling devices are all duplicated and arranged so that they can be operated from either the front or the back of the control. Thus, the levers controlling the throttle and ignition of the motor are duplicated, and can be op erated from either the front ortheback of the control. The reversing levers 16 and the speed changing levers 35 are geared together so that the movements'made by the operator in manipulating these levers is the same whether he is seated at the front or the back of the control. The smallest "pipe 9 and the pipe 10 which are connected to the change speed gearing of the motor vehicle are locked in their neutral and both of their shifted positions. The largest pipe 11 which is connected to the reversing gearing of the tractor is locked in its neutral and shifted positions, since the reversing levers 16 engage in the notches 21 in the neutral position of the largest pipe 11, and against the shoulders 22 in the shifted positions of said largest pipe. The largest pipe 11 con trols both the forward and backward move-' ment of the motor vehicle, and hence the gearing which causes the forward movement and the gearing which causes-the backward movement cannot be placed in operation at the same time. .The smallest pipe 9 and the pipe 10 control the change speed gearing, and since the smallest pipe 9 and thepipe 10 are operated one at a time by the speed changing levers 35, the gearing for only one speed can be placed in operation at any one time. The pipes 9, 10 and 11 are locked when the clutch is in its operative position, and consequently, the change speed gearing and the reversing gearing cannot be operated while the clutch is in its operative position. .The clutch pedals are manipulated by the same movements on the part of the operator whether he is seated in frontor in,

the back of. the control. The clutch is held out of its operative position by the locking action of the crank arm 77, the link 80 and' for which the motor vehicle is used; and

fee

each of the different speeds must be engageable while the motor vehicle is at rest. When the motor vehicle is at rest, it is very liable to happen that the parts of the change speed gearing which engage with each other are not in the proper position to so engage,

and often it is necessary to manipulate the clutch several times before such proper position is obtained. In the control shown and described, however, the springs 112 permit the speed changing levers 35 and the reversing levers 16 to be shifted and locked although the parts of the gearing which they control may not be in the position for en agement with each other.

'le for the purpose of illustration, I have shown my invention embodied in a control for a tractor, the control embodying my invention may be used for other kinds of motor vehicles. Also, the control shown and described is designed for use in connection with change speed gearing which permits four speeds forward and four 'speeds backward; but my invention is not limited to this particular numberof speeds. It is apparent that other changes may be made in the construction which I have shown and described without departing from my invention, and I do not'wish to be limited to the details of the construction shown and described.-
